PROBLEM TO BE SOLVED: To provide a liquid crystal composition exhibiting an optically isotropic liquid crystal phase over a wide temperature range, and an optical element (for example, a liquid crystal display element) using them. SOLUTION: A compound in which a dendron having a branching degree of 2 to 5 and a rod-shaped mesogen are linked at a focal point is converted into a mother liquid crystal composition, for example, a mother liquid crystal composition containing an achiral liquid crystal compound and a chiral agent. A liquid crystal composition which is added. An optical device using such a liquid crystal composition. [Selection figure] None |
